Seth Grahame-Smith, author of the best-selling books "Pride and Prejudice and Zombies" and "Abraham Lincoln, Vampire Hunter," tweeted the following pic today:

Accompanying the rather intriguing photo was a line familiar to "Beetlejuice" fans: "It's Showtime!"

Could Grahame-Smith be teasing a new "Beetlejuice" movie?

Well, in 2011 Warner Bros. hired the writer to pen the sequel sooooo...yeah, maybe. The big news might be that this sequel is finally getting off the ground -- but will Tim Burton and Michael Keaton return? I'm especially curious about Keaton, considering all the hemming-and-hawing-and-denying Bill Murray has done about "Ghostbusters 3." Then again, can there really be a "Beetlejuice" without Michael Keaton?
